` Specification of Letters Patent. y Application filed March 17, 1914. Serial No;825,335.

To all fr0/10m z'z may concern: y

Be it known that l, HENRY C. HIEN, a citizen of the United States, residing at Vfebb City, in the county of Jasper and State of Missouri, have invented new and useful Improvements in WVrenches, of which the following is a specification.

The present invention relates toimprovements in wrenches adapted -for use in connection with flanged sleeves, to secure the said sleeves upon a pipe, and to arrange the same to be connected'with afiange or similar sleeve upon a second section of pipe, and the improvement resides inthe construction, combination and operative arrangementof parts set forth in the following specification and falling within the In the drawing: Figure l is a perspective view illustrating the wrench in operative position upon the flange of a sleeve and in the act of screwing the sleeve upon a sec tion of pipe, F ig. 2 is a central vertical lon-- gitudinal sectional view'through the wrench, and F ig. 3 is a transversey sectional y'view approximately on the line 3 3 of Fig. 2.

In screwing a flanged collar, or what is usually lmown as a union sleeve upon a pipe section, an ordinary wrench is practically useless, especially upon the flanges of such unions which are of a greater diameter than the distance between the jaws of a wrench. Therefore, itis not an uncommon practice to insert two bolts in two oppositely threaded openings in the flange of the union and arrange therebetween a bar to permit of the'opposite sides or edges of the said bar contacting with the bolt when pressure is applied to the bar to rotate the union in a screwing direction.

Such arrangement is crude and requires an amount of time in placing the bolts in the bolt openings in the flange of the union,l and it may therefore be considered the primary object of the present invention to provide a wrench which may be easily and quickly adjusted to engage with the varysaid union to thread the same upon a pipe section or remove the same from a pipe section as occasionrequires.

My improved wrench includes a lever l which is preferablyrectangular in cross sec tion, and which has one of its faces, which, for the sake of'convenience, I will term its upper face, provided withsa centrally arin the flange 4 of f tially rectangular The block or teeth 2, the saine beingforined -byv depressing the lever One of the 'ends'-v Patented sept/-8, yi914.

The pivotal connection between the block and dog is preferably loose and by reference to Figs. l and 2 of the drawings it will be noted that the angular toothed end of the dog, which engages one ofthe depressions or against the rear end of the block or dog, so a pressure upon the jaw will be delivered directly upon the" lar or lieving the remainder of the dog from strain. It will be obvious thatl when the teeth or serrations 9-of one of thecorners of the block or jaw 7 is swung into engagement anguwith the periphery of the flange Il,v after the finger, 3 has been arranged within one of the bolt openings of the flange, the union may be easily and quickly screwed upon the pipe section `6, and by teeth of `the lever, liesL y toothed end 'of thefdog,` thus re-v reversing the kposition. of

the wrench the said union may be readily unscreWed from the pipe section as described.

From the above description, taken in connection with the accompanying drawing, the simplicity of the device as Well as the advantages thereof will it is thought, loe perectly apparent to those skilled in the art to which such invention appertains Without further detailed description.

Having thus described the invention, What I claim is:

- l. A. flange Wrench comprising a lever having a projecting finger at one of its ends, a rectangular block Aslidably mounted upon the lever and removable therefrom, said block having arcuate corners which are provided with longitudinally extending teeth, and spring pressed means upon the block co-acting With the lever for llocking the liloclrupon the lever.

A Wrench for applyingl and removing anged sleeves to and from pipes comprising a flat rectangular lever havingone of its ends provided with a projecting finger to tit an kopening in ing its outer face provided with a seriesof spaced transverse indentures, and reversible rectangular block arranged for slidahle movement upon the lever, ears upon the block, a substantially L-shaped dog Copies -of this patent may be obtained` forve cents each, by `addressing the 'to lit an opening in the sleeve,

pivcted to the ears, a spring between the tail of the dog and the block and the angular toothed portion ofthe dog adapted to'lie against one of the faces or' the block and engaged in one of the indentures.

3. A Wrench for applying and removing hanged sleeves to and from pipes comprising a fiat rectangular lever having one o its ends provided with a projecting linger said lever having its outer face provided with a series of spaced transverse indentures, a rectangular block having a rectangular' opening adjacent one of its aces to permit of the block being arranged upon the lever and 'from either of the ends of the block, the said block having arcuate corners which are provided With longitudinal teeth to engage with the lla-nge of the sleeve, a spring pressed dog carried hy the block and having a flat toothed vportion which is adapted to Contact with one of the ends of the block and engaged in one or the indentures of the lever.

In testimony whereof I affix my signature in presence of two Witnesses.`
